The content of casein kinase 2 is considerably decreased in ribosome-free extracts of the frontal cortex of schizophrenic and Alzheimer's disease patients in comparison to normal brains as has been demonstrated by means of immunoblotting. The activity of casein kinase 2 towards endogenous substrates and casein is also diminished in the cases of mental pathologies examined. This phenomenon may explain the well-known aberrations in the phosphorylation of structural proteins of human brain which are intrinsic for the mental diseases.
通过免疫印迹法已证实,与正常大脑相比,精神分裂症和阿尔茨海默病患者额叶皮质的无核糖体提取物中酪蛋白激酶2的含量显著降低。在所研究的精神病理学病例中,酪蛋白激酶2对内源性底物和酪蛋白的活性也有所降低。这一现象可能解释了人类大脑结构蛋白磷酸化中众所周知的异常,而这些异常是精神疾病所固有的。
